It's a good idea to close redundant or unused accounts you do not consider necessary. Here are a few reasons why:
It's best to cut up and return to the issuer any cards you don't want. Refuse to accept renewal cards you don't plan to use. You'll want to contact each card issuer to determine specific account closing requirements. Ask for a confirmation letter of the closing and check that it is listed on your credit report as having been "closed at the customer's request."
